cuE'rAIN-STRETCHER.

Be it' known that we, J or'VIN STwARTz.,`-re siding at Homestead, and DAvrD ANDERSON,

residing at Pittsburg, county of Alle he'ny,'

Pennsylvania, citizens of the United tates, have invented certain new and useful Improvements in Curtain-Stretchers, of which the following is a' specification, reference be-" had therein to the accompanying drawm s. gThis invention relates to a curtain stretcher, and the object of the invention is to provide a novel frame u on which curtains can be stretched either or drying or bleaching the same..

lAnother object of this invention is to provide a' frame wherein positive and reliable i means are provided-for stretchingA a curtain without tearing or injuring the same.

A further object of this invention is to provide an adjustable and collapsible frame, that can be folded l same is notbeing used.

An important characteristic of this invention-is the stretching means com rising slidable bars provided with pivote projecting i pins, these pins being drawn into the frame when not muse, and when in use are pro` jected at an angle from the frame to stretch a curtain thereon.

' 'The detail constructionientering into our invention` will bev presently described and then specifically pointed out in the appended the side .rails 3 and 4 clalms.

I n the drawings forming a. part ofthis' specification: Figure`1 is 'a front elevation of the curtain' stretcher, Fig. 2 is a lan of the same, Fig. 3 is a rear 'elevation of t e curtain ystretcher, Fig. 4 an end view` of the same,

Fig. 5 a longitudinal sectional view taken on the line --w of Fig. 3, and Fig. 6 is a cross sectional view taken on the line y-y of Fig. 5.

To put our invention into practice, We construct the. curtain stretcher of a rectangular frame comprising-'a top rail 1, a bottom rail 2', side rails 3 and 4, and pivoted supports 5, vthese supports being yst/raps 5. The free -ends of the supports l5gare provided with prongs 7, to prevent said .supportsfrom slipping, when, supporting the frame of a cur-tam The side rails 3 and 4' are-detachably ment with one another by a clamp '15 and a screw 16, said cleat beingl into a'small parcel, when the assembled, the grooves and cutaway 2, that the slide bars rivotally connected to nected to the top rail 1 by stra s 8, carried byvv the upper ends ofsaidslde ral s, these strapsembracin the topv rail 1 and having their ulpper en s connected together lby 'winged t umb screws 9., 1

One end of the bottom rail 2 is'provided with straps 10, whereby said bottom rail can be connected'to the .side'rail 3similar to the connections' of the siderails with th`e to rail.

The op osite end of the bottom rail 2 ies in frontogthe side rail 4 and is detachably connected thereto by a yoke clamp 11 and a screw 1 2.

The top and bottom rails 1 and 2'are made in twoV parts, theparts of said rails being hinged together, as at 13., whereby when the frame is knocked down, the top and bottom rails which are of a considerable length can be folded.. When said rails are being used, thepa'rt's'of the rails are` maintained in aline# cleat 14, a yoke iixedto one ofthe parts ofthe top rail 1.I

lReference will noW be .had to the mechanism employed for stretching a the frame.l y

The inner edges of the top, bottom and side rails/aref provided with longitudinally dis-.

posed. grooves 17 e ually s aced angular` grooves 18 having'shoiilders 19ormed at right angles to "the-grooves 17. v The inneredges of v the rails are-also cut awa as .at 20, theobvgrooves 17 of the ralls are mounted slide bars 21, these slide bars carrying ivot pins 22, which protrude into the angu ar grooves 18 of said rails. with buttons 22, the Shanks 23 of which f Patented June 1c', 1908i.'

- Thes'lide bars'21 are provided curtain upon extend through the .cut away portions\20` of said rails:

position at right ang esto. said slide bars.

Itwill ofcourse be understood that in conv f 85 y jecteof whichwill present y appear. In the This movement of the pins tendsftnstretch a curtain u on the frame, without injuring the same, t e pins moving in unison.

The slide bars are arranged in the top 'and' bottom rails 1 and 2, whereby when the slide bar in one part of the rail is moved, `it will contact `*wit the end of the slide bar in the .adjoining part of the rail, consequently with one movementv of the button, the ins in the whole rail. can'v be moved outwar y. It is, however, necessary to manipulate both button'sona rail in order to return the pins to their normal position, and it is essential that the pins bewithdrawnA into the to and bottom rails, before said rails can e folded. This is due to thefact that the `Slide bar of one part of the rail, protrudes into the adjoining part of'the rail, whenthe pins are V projecting from the rail.

It is thought that our -invention will be fully understood rom'the above description taken in connection with the drawings, and it is obvious that such variations in the invention as yare permissible by the appended claims'can beresorted to lwithout departing from the scope of the invention.

Having now described our invention what we claim as new, is

- 1. A curtain stretcher embodying a frame consisting of rails detachably connected together, su ports pivotally connected to some of 'said ral si, the other of said rails compris'- I ing -two hinged arts, a clamp for retaining ysaid parts iii a nement with one another,I Vsaid rails. having grooves formed therein,

slide bars mounted in said grooves, pivoted pins'carried by. said slide bars and adapted f to .project from said rails, buttons for mov- Ving said slide bars, and strips covering said grooves and slide bars. j 2. A curtain stretcher comprising railsl detachably connected together yto provide a rectangular frame, pivoted supports carried by some of-4 said rails for .sup orting said `frame,said rails havin grooves ormed therein,"slide bars mounte 1n saidgrooves, pivoted pins carried by'said bars and lying at an project saidpins ati-right bars, and means for supportingsaid i 'frame atan inclination.

4. A curtain stretcher comprising ,a frame, of rails detachable one from the other, slide y bars mounted in said rails, pivoted pinsl carried by said slide'bars, and normallylyin at barsltofproject said pins from said rails, and means or supporting said frame. j
